[PATCH v3 3/4] arm64: dts: freescale: Add support for the Variscite i.MX8MP DART8MCustomBoard

Laurent Pinchart laurent.pinchart at ideasonboard.com
Sat Jun 8 11:04:46 PDT 2024


The DT8MCustomBoard is a carrier board for DART i.MX8-based modules.
This device tree file adds support for the DT8MCustomBoard v2.0 with a
connected DART-MX8M-PLUS module.

Signed-off-by: Laurent Pinchart <laurent.pinchart at ideasonboard.com>
---
Changes since v2:

- Add HDMI support
- Set SION for I2C* GPIO recovery pinctrl groups

Changes since v1:

- Make reg second property in touch at 0 and can at 1 nodes
- Drop unneeded status = "okay"
- Move status = "disabled" to end of node
- Rename can0-osc node with generic clock- prefix
